Description

Technical Field

[0001] This application relates to the technical field of hot pressing, and particularly to a hot pressing device. Background Art

[0002] In the manufacture of certain products, such as keyboard production, it is necessary to install some components (such as Bumper components) onto the product by hot pressing to increase the impact resistance of the product and extend its service life. However, there are some problems in this process. Due to the dimensional tolerance of the components (i.e., the difference between the actual size and the standard size of the components) and the inaccuracy of manual assembly, there may be deviations in the installation of the components onto the product. Such deviations may result in the product after hot pressing not meeting the requirements, thereby reducing the yield rate of the product. Summary of the Utility Model

[0003] In view of this, this application provides a hot pressing device to improve the technical problems of large assembly errors and low product yield rate in the existing hot pressing device.

[0004] An embodiment of this application provides a hot pressing device, which includes a workbench, a hot pressing mechanism, and a positioning mechanism. The hot pressing mechanism is arranged on the workbench and is configured to hot press a first workpiece and a second workpiece. The positioning mechanism includes a first positioning component and a second positioning component. The first positioning component is configured to fix the first workpiece. The second positioning component is arranged on the first positioning component, and the first positioning component is configured to drive the second positioning component and the first workpiece to move relative to the workbench. The second positioning component is configured to fix the second workpiece, and the second positioning component is configured to drive the second workpiece to move relative to the first positioning component.

[0005] In the above hot pressing device, the first positioning component drives the first workpiece and the second positioning component to move to the target position. After moving to the target position, the second positioning component drives the second workpiece to move relative to the first positioning component, that is, drives the second workpiece to move relative to the first workpiece, so as to adjust the assembly position between the first assembly part in the first workpiece and the second assembly part in the second workpiece. Thus, it can ensure the precise alignment of the first assembly part in the first workpiece and the second assembly part in the second workpiece, reduce the problem that the product after hot pressing does not meet the requirements due to the assembly error between the first workpiece and the second workpiece, and improve the yield rate of the product.

[0006] In at least one embodiment, the first positioning component includes a first driving member, a second driving member, and a first carrier for fixing the first workpiece. The first driving member and the second driving member are both installed on the workbench. The first driving member is connected to the first carrier and is configured to drive the first carrier to move along a first direction. The second driving member is connected to the second positioning component and is configured to drive the second positioning component to move along the first direction.

[0007] In the above embodiments, when the hot pressing mechanism hot presses the first workpiece and the second workpiece, the first driving member drives the first carrier member to move along the first direction to the target position, and the second driving member drives the second positioning assembly to move along the first direction to the target position. After both the first carrier member and the second positioning assembly move to the target positions, the hot pressing mechanism hot presses the first workpiece and the second workpiece. Thereby, it helps to ensure that the hot pressing mechanism accurately hot presses the first workpiece and the second workpiece.

[0008] In at least one embodiment, the first carrier member is provided with a moving space, and at least a part of the second positioning assembly is located in the moving space. When the second positioning assembly moves relative to the first positioning assembly, the second positioning assembly slides within the moving space.

[0009] In the above embodiments, during the process that the second positioning assembly drives the second workpiece to move relative to the first workpiece, the second positioning assembly is always located within the moving space. Thereby, the moving range of the second positioning assembly can be reduced, making the structure of the hot pressing device more compact and reducing the overall occupied space of the hot pressing device.

[0010] In at least one embodiment, the second positioning assembly is provided with a mating portion, and the moving space is provided with a stop portion, and the stop portion is configured to stop the mating portion to restrict the moving range of the second positioning assembly.

[0011] In the above embodiments, when the second driving member drives the second positioning assembly to move relative to the first positioning assembly, the stop portion in the moving space abuts against the mating portion in the second positioning assembly to hinder the movement of the second positioning assembly and restrict the moving range of the second positioning assembly. Thereby, the risk that the second positioning assembly disengages from the moving space due to excessive moving distance and increases the assembly error between the first workpiece and the second workpiece can be avoided, thereby further improving the product yield of the hot pressing device.

[0012] In at least one embodiment, the second positioning assembly includes a third driving member and a second carrier member for fixing the second workpiece. The second carrier member is mounted on the third driving member. The third driving member is connected to the second driving member and is configured to drive the second carrier member to move along a second direction, and the second direction intersects with the first direction.

[0013] In the above embodiments, when the first workpiece and the second positioning assembly move to the target positions, the second driving member drives the third driving member to move along the first direction, that is, drives the second workpiece to move along the first direction, and the third driving member drives the second carrier member to move along the second direction, that is, drives the second workpiece to move along the second direction. Through the cooperation of the third driving member and the second driving member, the second workpiece can move in two directions to adjust the position between the first workpiece and the second workpiece, so that the first fitting portion in the first workpiece and the second fitting portion in the second workpiece are accurately aligned, thereby ensuring the accuracy of the hot pressing process of the hot pressing device and improving the product yield.

[0014] In at least one embodiment, the hot pressing mechanism includes a mounting frame, a fourth driving member, and a hot pressing assembly. The mounting frame is disposed on the workbench, the fourth driving member is mounted on the mounting frame, the hot pressing assembly is connected to the fourth driving member, and the fourth driving member is configured to drive the hot pressing assembly to move along a third direction to hot press a first workpiece and a second workpiece, and the third direction intersects with the first direction and the second direction.

[0015] In the above embodiment, when the first workpiece and the second workpiece move to the target position and the first assembly portion of the first workpiece is accurately aligned with the second assembly portion in the second workpiece, the fourth driving member drives the hot pressing assembly to move along the third direction towards the direction close to the workbench, so that the hot pressing assembly hot presses the connection portion of the first workpiece and the second workpiece. Thereby, a fixed connection between the first workpiece and the second workpiece is achieved.

[0016] In at least one embodiment, the hot pressing device further includes a vision photographing assembly, and the vision photographing assembly is configured to acquire images of the first workpiece and the second workpiece to detect the assembly accuracy of the two.

[0017] In the above embodiment, through the arrangement of the vision photographing assembly, the assembly accuracy of the first workpiece and the second workpiece can be detected before hot pressing the first workpiece and the second workpiece, so as to ensure the accurate alignment of the first workpiece and the second workpiece, which is beneficial to the accurate hot pressing of the hot pressing device, improve the hot pressing quality of the hot pressing device, prevent unqualified products from entering the subsequent production stage, and thus improve the yield of the products.

[0018] In at least one embodiment, the workbench is provided with a first station, a second station, and a third station. The first station, the second station, and the third station are distributed along the first direction. The vision photographing assembly is disposed at the second station, and the hot pressing mechanism is disposed at the third station; the first positioning assembly is configured to drive the second positioning assembly and the first workpiece to sequentially move to the first station, the second station, and the third station.

[0019] In the above embodiment, by providing the first station, the second station, and the third station, and configuring the first positioning assembly to drive the first workpiece and the second positioning assembly to sequentially move to the first station, the second station, and the third station, it is beneficial to ensure that the first workpiece and the second workpiece are hot pressed and fixed after being accurately aligned, so as to reduce the problem that the products after hot pressing do not meet the requirements due to the assembly error between the first workpiece and the second workpiece, thereby further improving the yield of the products.

[0020] In at least one embodiment, the first carrier is provided with a first limiting portion, and the first limiting portion is configured to cooperate with the limiting hole in the first workpiece to restrict the position of the first workpiece; the second carrier is provided with a second limiting portion, and the second limiting portion is configured to cooperate with the limiting hole in the second workpiece to restrict the position of the second workpiece.

[0021] In the above embodiments, through the settings of the first limiting portion and the second limiting portion, it is not only beneficial to fix the first workpiece on the first carrier and the second workpiece on the second carrier, thereby improving the assembly efficiency. At the same time, it can also prevent any unnecessary movement of the first workpiece and the second workpiece during the hot pressing process, thereby ensuring the quality of hot pressing.

[0022] In at least one embodiment, the first carrier is further provided with an adsorption portion, and the adsorption portion is configured to adsorb the first workpiece.

[0023] In the above embodiments, when the first workpiece is fixed to the first carrier, the adsorption portion can adsorb the first fixing member, thereby further improving the fixing stability of the first workpiece, avoiding any unnecessary movement of the first workpiece during the hot pressing process, and ensuring the quality of hot pressing.

[0083] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present application. The terms used in the specification of the present application herein are only for the purpose of describing specific implementation manners, and are not intended to limit the present application.

[0085] An embodiment of the present application provides a hot pressing device. The hot pressing device includes a workbench, a hot pressing mechanism, and a positioning mechanism. The hot pressing mechanism is disposed on the workbench, and the hot pressing mechanism is configured to hot press a first workpiece and a second workpiece. The positioning mechanism includes a first positioning component and a second positioning component. The first positioning component is configured to fix the first workpiece. The second positioning component is disposed on the first positioning component, and the first positioning component is configured to drive the second positioning component and the first workpiece to move relative to the workbench. The second positioning component is configured to fix the second workpiece, and the second positioning component is configured to drive the second workpiece to move relative to the first positioning component.

[0086] In the above-mentioned hot pressing device, the first positioning component drives the first workpiece and the second positioning component to move to a target position (specifically, the position where the hot pressing mechanism is located). After moving to the target position, the second positioning component drives the second workpiece to move relative to the first positioning component, that is, drives the second workpiece to move relative to the first workpiece, so as to adjust the assembly position between the first assembly part in the first workpiece and the second assembly part in the second workpiece. Thus, it can ensure the accurate alignment of the first assembly part in the first workpiece and the second assembly part in the second workpiece, reduce the problem that the product after hot pressing does not meet the requirements due to the assembly error between the first workpiece and the second workpiece, and improve the yield of the product.

[0087] Next, some implementation manners of the present application will be described in detail with reference to the accompanying drawings. Without conflict, the following implementation manners and the features in the implementation manners can be combined with each other.

[0088] An embodiment of the present application provides a hot pressing device 100, as Figure 1 shown. The hot pressing device 100 includes a workbench 110, a hot pressing mechanism 120, and a positioning mechanism 130. The hot pressing mechanism 120 is disposed on the workbench 110, and the hot pressing mechanism 120 is configured to hot press a first workpiece 200 and a second workpiece 300.

[0089] Specifically, as Figure 6 and Figure 7As shown, the first workpiece 200 is provided with a first assembly part 210, the second workpiece 300 is provided with a second assembly part 310 that cooperates with the first assembly part 210, and the hot pressing mechanism 120 hot presses the first assembly part 210 and the second assembly part 310 to fix the first workpiece 200 to the second workpiece 300.

[0090] Exemplarily, the first workpiece 200 is a keyboard, the second workpiece 300 is a Bumper assembly, the Bumper assembly 300 is provided with a protruding part, and the protruding part is the second assembly part 310. The keyboard 200 is provided with a groove that cooperates with the protruding part 310, and the groove is the first assembly part 210.

[0091] When it is necessary to fix the Bumper assembly 300 to the keyboard 200, the user first snaps the protruding part 310 in the Bumper assembly 300 into the groove 210 in the keyboard 200. Subsequently, the hot pressing mechanism 120 hot presses the connection part between the Bumper assembly 300 and the keyboard 200 (specifically, the part where the protruding part 310 and the groove 310 cooperate) so that the Bumper assembly 300 is fixedly installed on the keyboard 200.

[0092] In some embodiments, as Figure 1 and Figure 9 shown, the positioning mechanism 130 includes a first positioning component 131 and a second positioning component 132. The first positioning component 131 is configured to fix the first workpiece 200. The second positioning component 132 is disposed on the first positioning component 131, and the first positioning component 131 is configured to drive the second positioning component 132 and the first workpiece 200 to move relative to the workbench 110. The second positioning component 132 is configured to fix the second workpiece 300, and the second positioning component 132 is configured to drive the second workpiece 300 to move relative to the first positioning component 131.

[0093] When it is necessary to hot press the first workpiece 200 and the second workpiece 300, the first positioning component 131 first drives the first workpiece 200 and the second positioning component 132 to move to the target position (specifically, the position where the hot pressing mechanism 120 is located). Subsequently, the second positioning component 132 drives the second workpiece 300 to move relative to the first positioning component 131, that is, drives the second workpiece 300 to move relative to the first workpiece 200 to adjust the position between the first assembly part 210 in the first workpiece 200 and the second assembly part 310 in the second workpiece 300. Finally, the first workpiece 200 and the second workpiece 300 are hot pressed by the hot pressing mechanism 120.

[0094] It should be noted that through the cooperation of the first positioning component 131 and the second positioning component 132, the hot pressing device 100 can adjust the assembly position between the first workpiece 200 and the second workpiece 300 to ensure the precise alignment of the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300, reducing the problem that the product after hot pressing does not meet the requirements due to the assembly error between the first workpiece 200 and the second workpiece 300, thereby improving the yield of the product.

[0095] It is worth noting that while the first workpiece 200 is fixed to the first positioning component 131 and the second workpiece 300 is fixed to the second positioning component 132, the cooperation between the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300 can be completed.

[0096] In other embodiments, the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300 can also be assembled and cooperated in a subsequent process, and the present application does not limit this.

[0097] Define the first direction X as the direction in which the first positioning component 131 drives the first workpiece 200 and the second positioning component 132 to move towards the hot pressing mechanism 120. In short, the first direction X is the conveying direction of the first workpiece 200. Define the second direction Y and the third direction Z to intersect pairwise with the first direction X. Among them, the definitions of the "first direction X", "second direction Y", and "third direction Z" are for facilitating the description of the relative position relationship of relevant structures, rather than indicating that the "first direction X", "second direction Y", and "third direction Z" need to rely on the relevant structures involved in the above definitions. Exemplarily, the first direction X, the second direction Y, and the third direction Z are pairwise perpendicular to each other.

[0098] In some embodiments, such as Figures 1 to 5 、 Figure 9 shown, the first positioning component 131 includes a first driving member 1311, a second driving member 1312, and a first carrier 1313 for fixing the first workpiece 200. Both the first driving member 1311 and the second driving member 1312 are installed on the workbench 110. The first driving member 1311 is connected to the first carrier 1313 and is configured to drive the first carrier 1313 to move along the first direction X. The second driving member 1312 is connected to the second positioning component 132 and is configured to drive the second positioning component 132 to move along the first direction X, which helps to ensure that the hot pressing mechanism 120 accurately hot presses the first workpiece 200 and the second workpiece 300.

[0099] Understandably, before the hot pressing mechanism 120 hot presses the first workpiece 200 and the second workpiece 300, the first driving member 1311 drives the first carrier 1313 to move along the first direction X to the target position, and the second driving member 1312 drives the second positioning assembly 132 to move along the first direction X to the target position. After both the first carrier 1313 and the second positioning assembly 132 move to the target positions, the hot pressing mechanism 120 hot presses the first workpiece 200 and the second workpiece 300.

[0100] In other embodiments, the first positioning assembly 131 can also drive the first carrier 1313 and the second positioning assembly 132 to move along the first direction X simultaneously through a single driving member, which is beneficial to simplifying the structure of the hot pressing device 100 and facilitating the maintenance or replacement of the hot pressing device 100.

[0101] In some embodiments, the first driving member 1311 drives the first carrier 1313 to move along the first direction X to the target position synchronously with the second driving member 1312 driving the second positioning assembly 132 to move along the first direction X to the target position.

[0102] In other words, the first driving member 1311 and the second driving member 1312 drive the first carrier 1313 and the second positioning assembly 132 to move simultaneously, which helps to save the waiting time for the assembly of the first workpiece 200 and the second workpiece 300.

[0103] In other embodiments, the first driving member 1311 driving the first carrier 1313 to move along the first direction X to the target position and the second driving member 1312 driving the second positioning assembly 132 to move along the first direction X to the target position may also be asynchronous.

[0104] For example, the first driving member 1311 first drives the first carrier 1313 to move to the target position, and then the second driving member 1312 drives the second positioning assembly 132 to move to the target position and assembles the second workpiece 300 with the first workpiece 200.

[0105] In some embodiments, as Figure 9 and Figure 10 shown, the first driving member 1311 includes a first slide rail 13111 and a first motor 13112. The first slide rail 13111 is arranged on the workbench 110 along the first direction X. The first motor 13112 is connected to the first slide rail 13111, and the first carrier 1313 is slidably mounted on the first slide rail 13111. The second driving member 1312 includes a second slide rail 13121 and a second motor 13122. The second slide rail 13121 is mounted on the workbench 110 along the first direction X, and the second motor 13122 is connected to the second slide rail 13121.

[0106] Understandably, before the hot pressing mechanism 120 hot presses the first workpiece 200 and the second workpiece 300, the first motor 13112 drives the first carrier 1313 to move along the first slide rail 13111 in the direction close to the hot pressing mechanism 120 until it moves to the target position. The second motor 13122 drives the second positioning component 132 to move along the second slide rail 13121 in the direction close to the hot pressing mechanism 120 until it moves to the target position.

[0107] In other embodiments, the first motor 13112 and the second motor 13122 can also be replaced by power sources such as cylinders and hydraulic cylinders, and the present application does not limit this.

[0108] In some embodiments, as Figure 9 , Figure 11 and Figure 12 shown, the first carrier 1313 is provided with a moving space 13131, and at least a part of the second positioning component 132 is located in the moving space 13131. When the second positioning component 132 moves relative to the first positioning component 131, the second positioning component 132 slides in the moving space 13131.

[0109] Understandably, when the first positioning component 131 and the second positioning component 132 move to the target position, the second driving member 1312 drives the second positioning component 132 to move relative to the first positioning component 131 to adjust the relative position between the first workpiece 200 and the second workpiece 300, so that the first assembly portion 210 in the first workpiece 200 is accurately aligned with the second assembly portion 310 in the second workpiece 300.

[0110] During the process of the second positioning component 132 driving the second workpiece 300 to move relative to the first workpiece 200, the second positioning component 132 is always located in the moving space 13131. Thus, the moving range of the second positioning component 132 can be reduced, making the structure of the hot pressing device 100 more compact and reducing the overall occupied space of the hot pressing device 100.

[0111] It should be noted that during the synchronous movement of the first carrier 1313 and the second positioning component 132, the second positioning component 132 is always located in the moving space 13131. In this way, it is beneficial to ensure that the relative position between the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300 remains unchanged, thereby reducing the assembly error between the first workpiece 200 and the second workpiece 300, saving the time for subsequent alignment adjustment between the first assembly portion 210 and the second assembly portion 310, and improving the working efficiency of the hot pressing device 100.

[0112] In some embodiments, the second positioning component 132 is provided with a mating portion 1323, and the moving space 13131 is provided with a stop portion 13132, which is configured to stop the mating portion 1323 to restrict the moving range of the second positioning component 132.

[0113] Specifically, the first carrier 1313 protrudes into the moving space 13131 with a first bump (not shown in the figure) to form the above-mentioned stop portion 13132, and the second positioning component 132 is provided with a second bump (not shown in the figure) to form the above-mentioned mating portion 1323. When the second driving member 1312 drives the second positioning component 132 to move relative to the first positioning component 131, the first bump abuts against the second bump to hinder the movement of the first positioning component 131 and restrict the moving range of the second positioning component 132.

[0114] By providing the mating portion 1323 and the stop portion 13132, it is possible to avoid the risk that the second positioning component 132 disengages from the moving space 13131 due to excessive moving distance, increasing the assembly error between the first workpiece 200 and the second workpiece 300, thereby further improving the product yield of the hot pressing device 100.

[0115] In some embodiments, as Figure 9 and Figure 10 shown, the second positioning component 132 includes a third driving member 1321 and a second carrier 1322 for fixing the second workpiece 300. The second carrier 1322 is mounted on the third driving member 1321. The third driving member 1321 is connected to the second driving member 1312 and is configured to drive the second carrier 1322 to move along the second direction Y.

[0116] It can be understood that when the first workpiece 200 and the second positioning component 132 move to the target position, the second driving member 1312 drives the third driving member 1321 to move along the first direction X, that is, drives the second workpiece 300 to move along the first direction X, and the third driving member 1321 drives the second carrier 1322 to move along the second direction Y, that is, drives the second workpiece 300 to move along the second direction Y.

[0117] Thereby, precise alignment between the first assembly portion 210 of the first workpiece 200 and the second assembly portion 310 of the second workpiece 300 is achieved, reducing the problem that the product after hot pressing does not meet the requirements due to the assembly error between the first workpiece 200 and the second workpiece 300, thereby improving the product yield.

[0118] In short, through the cooperation of the third driving member 1321 and the second driving member 1312, the second workpiece 300 can be moved in two directions (specifically, the first direction X and the second direction Y) to adjust the position between the first workpiece 200 and the second workpiece 300, so that the first fitting portion 210 in the first workpiece 200 is accurately aligned with the second fitting portion 310 in the second workpiece 300, thereby ensuring the accuracy of the hot pressing process of the hot pressing device 100 and improving the yield of the product.

[0119] In other embodiments, the second positioning assembly 132 may also drive the second workpiece 300 to move in two directions through a separate third driving member 1321. The present application does not limit this, and those skilled in the art can choose according to the actual situation.

[0120] In some embodiments, such as Figure 1 and Figure 13 shown, the hot pressing mechanism 120 includes a mounting frame 121, a fourth driving member 122, and a hot pressing assembly 123. The mounting frame 121 is disposed on the workbench 110 to provide stable support for the entire hot pressing mechanism 120. The fourth driving member 122 is mounted on the mounting frame 121, and the hot pressing assembly 123 is connected to the fourth driving member 122. The fourth driving member 122 is configured to drive the hot pressing assembly 123 to move along the third direction Z to hot press the first workpiece 200 and the second workpiece 300.

[0121] It can be understood that when the first workpiece 200 and the second workpiece 300 move to the target position and the first fitting portion 210 of the first workpiece 200 is accurately aligned with the second fitting portion 310 in the second workpiece 300, the fourth driving member 122 drives the hot pressing assembly 123 to move in the direction close to the workbench 110 along the third direction Z, so that the hot pressing assembly 123 hot presses the connection portion of the first workpiece 200 and the second workpiece 300 (specifically, the first fitting portion 210 and the second fitting portion 310), thereby realizing the fixed connection between the first workpiece 200 and the second workpiece 300.

[0122] In some embodiments, such as Figure 8 and Figure 13 shown, the hot pressing assembly 123 includes a pressing head 1231 and a heating member 1232. The heating member 1232 is installed in the pressing head 1231, and the pressing head 1231 is connected to the fourth driving member 122. When it is necessary to hot press the first workpiece 200 and the second workpiece 300, the fourth driving member 122 drives the pressing head 1231 to move in the direction close to the workbench 110 along the third direction Z and applies pressure to the connection portion of the first workpiece 200 and the second workpiece 300. At the same time, the heating member 1232 heats the connection portion of the first workpiece 200 and the second workpiece 300, thereby realizing the fixed installation of the first workpiece 200 on the second workpiece 300.

[0123] In some embodiments, the hot pressing assembly 123 further includes a guiding member 1233, and the guiding post is installed on the side of the pressing head 1231 facing the workbench 110. A guiding hole 13133 is provided on the first bearing plate. When the fourth driving member 122 drives the pressing assembly to move towards the workbench 110, the guiding post passes through the guiding hole 13133 and slides along the guiding hole 13133.

[0124] Through the arrangement of the guiding member 1233 and the guiding hole 13133, the guiding of the hot pressing assembly 123 can be realized, the risk of deviation of the hot pressing assembly 123 during movement can be reduced, thereby improving the hot pressing accuracy of the hot pressing device 100, and further improving the yield of the product.

[0125] In some embodiments, as Figure 1 and Figure 14 shown, the hot pressing device 100 further includes a vision photographing assembly 140, and the vision photographing assembly 140 is configured to acquire images of the first workpiece 200 and the second workpiece 300 to detect the assembly accuracy between the first workpiece 200 and the second workpiece 300. It should be noted that the vision photographing assembly 140 is configured to detect the assembly accuracy of the first workpiece 200 and the second workpiece 300 before the hot pressing mechanism 120 hot presses the first workpiece 200 and the second workpiece 300.

[0126] Through the arrangement of the vision photographing assembly 140, the assembly accuracy of the first workpiece 200 and the second workpiece 300 can be detected before hot pressing the first workpiece 200 and the second workpiece 300, so as to ensure the accurate alignment of the first workpiece 200 and the second workpiece 300, which is beneficial to the accurate hot pressing of the hot pressing device 100, improve the hot pressing quality of the hot pressing device 100, prevent unqualified products from entering the subsequent production stage, and further improve the yield of the product.

[0127] Still taking the Bumper assembly 300 and the keyboard 200 as an example below, before hot pressing the Bumper assembly 300 and the keyboard 200, the hot pressing device 100 acquires a first image of the Bumper assembly 300 and the keyboard 200 after assembly (specifically, the protruding portion 310 is clamped in the groove 210) through the vision photographing assembly 140. Subsequently, the hot pressing device 100 analyzes the assembly accuracy of the protruding portion 310 and the groove 210 in the first image through image processing software, such as whether the gap between the protruding portion 310 and the groove wall of the groove 310 is uniform.

[0128] If the gap between the protruding portion 310 and the groove wall of the groove 210 is uneven, that is, there is an assembly error, the hot pressing device 100 drives the Bumper assembly 300 to move in the first direction X and the second direction Y respectively through the second driving member 1312 and the third driving member 1321 to adjust the relative position between the Bumper assembly 300 and the keyboard 200, so that the protruding portion 310 is accurately aligned with the groove 210, that is, the gap between the protruding portion 310 and the groove wall of the groove 210 is uniform.

[0129] After the protruding portion 310 in the Bumper assembly 300 is accurately aligned with the groove 210 in the keyboard 200, the hot pressing device 100 hot presses the part where the protruding portion 310 in the first workpiece 200 and the second workpiece 300 is clamped in the groove 210 through the hot pressing mechanism 120, and the fixed connection between the Bumper assembly 300 and the keyboard 200 can be realized.

[0130] In some embodiments, such as Figure 1 and Figure 14 As shown, the vision photographing assembly 140 includes a CCD camera 142, a connecting member 143, and a fifth driving member 141. The CCD camera 142 is connected to the fifth driving member 141. The fifth driving member 141 is installed on the connecting member 143, and the connecting member 143 is installed on the mounting frame 121 of the hot pressing mechanism 120. The fifth driving member 141 is configured to drive the CCD camera 142 to move to a position where it is aligned with the first assembling portion 210 and the second assembling portion 310.

[0131] In other embodiments, the connecting member 143 may also be directly installed on the workbench 110, and the present application does not limit this.

[0132] In some embodiments, such as Figures 1 to 5 As shown, the workbench 110 is provided with a first station 111, a second station 112, and a third station 113. The first station 111, the second station 112, and the third station 113 are distributed along the first direction X. The vision photographing assembly 140 is disposed at the second station 112, and the hot pressing mechanism 120 is disposed at the third station 113. The first positioning assembly 131 is configured to drive the second positioning assembly 132 and the first workpiece 200 to move to the first station 111, the second station 112, and the third station 113 in sequence.

[0133] It can be understood that when both the first positioning assembly 131 and the second positioning assembly 132 are located at the first station 111, the user fixes the first workpiece 200 on the first carrier 1313, and at the same time fixes the second workpiece 300 on the second carrier 1322 to realize the assembly of the first workpiece 200 and the second workpiece 300, that is, the first assembling portion 210 is matched with the second assembling portion 310.

[0134] After the assembly of the first workpiece 200 and the second workpiece 300 is completed, the first positioning component 131 drives the first workpiece 200 and the second positioning component 132 to move to the second working station 112. At this time, the vision photographing component 140 acquires an image of the assembled first workpiece 200 and second workpiece 300, and detects the assembly accuracy between the first assembly portion 210 and the second assembly portion 310.

[0135] If there is an assembly error between the first assembly portion 210 and the second assembly portion 310, the hot pressing device 100 drives the second workpiece 300 to move in the first direction X and the second direction Y respectively through the second driving member 1312 and the third driving member 1321, so as to adjust the relative position between the second workpiece 300 and the first workpiece 200, so that the first assembly portion 210 and the second assembly portion 310 are accurately aligned.

[0136] After the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300 are accurately aligned, the first positioning component 131 drives the first workpiece 200 and the second positioning component 132 to move to the third working station 113. At this time, the hot pressing component 123 in the hot pressing mechanism 120 moves in the direction close to the workbench 110 to hot press the connection part of the first workpiece 200 and the second workpiece 300, thereby realizing the fixed connection between the first workpiece 200 and the second workpiece 300.

[0137] It should be noted that if there is no assembly error between the first assembly portion 210 and the second assembly portion 310, the first positioning component 131 directly drives the first workpiece 200 and the second positioning component 132 to move to the third working station 113.

[0138] By setting the first working station 111, the second working station 112 and the third working station 113, and configuring the first positioning component 131 to drive the first workpiece 200 and the second positioning component 132 to move to the first working station 111, the second working station 112 and the third working station 113 in sequence, it is beneficial to ensure that after the first workpiece 200 and the second workpiece 300 are accurately aligned, hot pressing and fixing are carried out, so as to reduce the risk that the product after hot pressing does not meet the requirements due to the assembly error between the first workpiece 200 and the second workpiece 300, thereby further improving the yield of the product.

[0139] In some embodiments, as Figure 11 and Figure 12 shown, the first carrier 1313 is provided with a first limiting portion 13134, and the first limiting portion 13134 is configured to cooperate with a limiting hole (not shown in the figure) in the first workpiece 200 to restrict the position of the first workpiece 200. The second carrier 1322 is provided with a second limiting portion 13221, and the second limiting portion 13221 is configured to cooperate with a limiting hole (not shown in the figure) in the second workpiece 300 to restrict the position of the second workpiece 300.

[0140] Understandably, when assembling the first workpiece 200 and the second workpiece 300, the user first fixes the first workpiece 200 to the first carrier 1313, and passes the first limiting portion 13134 through the limiting hole of the first workpiece 200. Subsequently, the user fixes the second workpiece 300 to the second carrier 1322 and passes the second limiting portion 13221 through the limiting hole of the second workpiece 300. At this time, the first assembling portion 210 in the first workpiece 200 cooperates with the second assembling portion 310 in the second workpiece 300, that is, the assembly of the first workpiece 200 and the second workpiece 300 is realized.

[0141] Through the settings of the first limiting portion 13134 and the second limiting portion 13221, it is not only beneficial to fix the first workpiece 200 on the first carrier 1313 and fix the second workpiece 300 on the second carrier 1322, thereby improving the assembly efficiency. At the same time, it can also prevent any unnecessary movement of the first workpiece 200 and the second workpiece 300 during the hot pressing process, thereby ensuring the quality of hot pressing.

[0142] In some embodiments, as Figure 12 shown, the first carrier 1313 is further provided with an adsorption portion 13135, and the adsorption portion 13135 is configured to adsorb the first workpiece 200. Specifically, an air suction hole (not shown in the figure) is provided on the first carrier 1313 to form the above-mentioned adsorption portion 13135. When the first workpiece 200 is fixed to the first carrier 1313, the air suction hole adsorbs the first workpiece 200. Through the setting of the adsorption portion 13135, the fixing stability of the first workpiece 200 can be further improved, thereby avoiding any unnecessary movement of the first workpiece 200 during the hot pressing process and ensuring the quality of hot pressing.

[0143] In other embodiments, the adsorption portion 13135 can also generate an adsorption force by using electromagnetic force or other means. For example, if the first workpiece 200 is made of a metal material, the adsorption portion 13135 can be an electromagnet that adsorbs the first workpiece 200 through electromagnetic force.

[0144] In some embodiments, the first positioning assembly 131 further includes a sensor 1314. The sensor 1314 is disposed on the first carrier 1313 and is configured to detect whether the first carrier 1313 is fixed with the first workpiece 200. Thereby, the risk of air compression in the hot pressing mechanism 120 can be reduced, the safe operation of the hot pressing device 100 can be ensured, and the working efficiency of the hot pressing device 100 can be improved.

[0145] In some embodiments, the working principle / process of the hot pressing device 100: In the initial state, both the first positioning component 131 and the second positioning component 132 are located at the first working station 111. At this time, the user fixes the first workpiece 200 to the first carrier 1313 and simultaneously fixes the second workpiece 300 to the second carrier 1322 to achieve the assembly of the first workpiece 200 and the second workpiece 300, that is, the first assembly portion 210 cooperates with the second assembly portion 310.

[0146] After the assembly of the first workpiece 200 and the second workpiece 300 is completed, the first positioning component 131 drives the first workpiece 200 and the second positioning component 132 to move to the second working station 112. At this time, the vision photographing component 140 acquires an image of the assembled first workpiece 200 and second workpiece 300 and detects the assembly accuracy of the first assembly portion 210 and the second assembly portion 310.

[0147] If there is an assembly error between the first assembly portion 210 and the second assembly portion 310, the hot pressing device 100 drives the second workpiece 300 to move in the first direction X and the second direction Y respectively through the second driving member 1312 and the third driving member 1321 to adjust the relative position between the second workpiece 300 and the first workpiece 200, so that the first assembly portion 210 and the second assembly portion 310 are accurately aligned.

[0148] After the first assembly portion 210 in the first workpiece 200 and the second assembly portion 310 in the second workpiece 300 are accurately aligned, the first positioning component 131 drives the first workpiece 200 and the second positioning component 132 to move to the third working station 113. At this time, the hot pressing component 123 in the hot pressing mechanism 120 moves in the direction close to the workbench 110 to hot press the connection portion of the first workpiece 200 and the second workpiece 300, thereby realizing the fixed connection between the first workpiece 200 and the second workpiece 300.

[0149] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application and are not used as a limitation to the present application. As long as it is within the scope of the substantial spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of the disclosure of the present application.
